The establishment of an authentic collective dwelling must seek, above all, an urban neighborhood notion as its leading principle: a meeting place shared as patrimony and symbol of a cordial coexistence and fundamental respect for otherness. In the Y Village, this premise is even more enhanced by the fact that it houses an entire family – as a small community: the elderly parents plus their three children, each one with its respective and distinct family configurations. Therefore, we unite these four ‘houses’ based on the quality of the desired places between them: a ground floor revealed as a square for family gatherings, voids that preserve the adequate light, ventilation and privacy – but still allowing a direct interaction between its residents through its interior balconies, besides the collective terrace on its roof. The units are conceived as a flexible system that defines strict services bands inside the entirely free plan to be organized by each family according to their present and future varied needs. Thereby, we adopt a modular, light and rational materiality, changing between the warm expression of wood in its interior and the more urban of its metal and polycarbonate surfaces. In a city where we have the predominance of large and ordinary real state developments, this is an architecture model that must be encouraged as an integrator agent of its inhabitants’ affections and where they can share their life routines in a wholesome way.
